Which equation represents the line that is perpendicular to y = 5 and passes through (-4,-3)?
kenny6666 [7]

Answer:

The required equation is: y=-3

Option D is correct.

Step-by-step explanation:

We need to write equation of line that is perpendicular to y = 5 and passes through (-4,-3).

The equation of line in slope-intercept form is expressed as: y=mx+b

where m is slope and b is y-intercept.

Finding Slope:

Comparing with the given equation y=5, the slope m =0

The slope of required line will be opposite reciprocal of 0 as both lines are perpendicular. so it will be m=0

Finding y-intercept

The y-intercept can be found using slope m=0 and point (-4,-3)

y=mx+b\\-3=0(-4)+b\\b=-3

So, y-intercept b is b=-3

The equation of required line having slope m=0 and y-intercept b=-3 is

y=mx+b\\y=0(x)-3\\y=-3

So, required equation is: y=-3

Option D is correct.

In describing a dataset, what does the standard deviation or standard error represent?
ivann1987 [24]
A measure of the variation around the estimate of the mean.

The standard deviation is a statistic that lets you know how tightly all the subjects are clustered around the mean in a set of data. A single standard deviation away from the mean in either of the directions accounts for somewhere around 68 % of data. If two standard deviations are away from the mean, it accounts for around 95% of data. If three standard deviations are away it accounts for 99% of the data.

1) The total range of variation in the dataset is called RANGE.

3) A measure of the variation around the estimate of the mean is SEM (STANDARD ERROR OF THE MEAN).

4) The most common value observed (highest frequency) is MODE.

Solve the system of equations.<br> 14x+5y=31<br> 2x−3y=−29 ​
Nastasia [14]

Answer:

  (x, y) = (-1, 9)

Step-by-step explanation:

A graphical solution can be quick and easy. It shows the solution to be ...

  (x, y) = (-1, 9)

__

Another suitable method is Cramer's rule. It makes use of a particular pattern of sum of products of coefficients and constants. The denominator in each case is the same sum of products.

  x = (5(-29)-(-3)(31))/(5(2)-(-3)(14)) = -52/52 = -1

  y = (31(2)-(-29)(14))/52 = 468/52 = 9
